The occurrence of this horsey festival on St. _Mark's_ Day may be connoted with the fact that in Welsh and Cornish _march_, in Gaelic _marc_, meant _horse_: obviously _marc_ is allied to the modern _mare_. There is a Rottenrow at Lewes, and Rottenrow Tower on the confines of Alnwick is suggestive of the more famous Rotten Row in London. It would seem that this site was also the bourne or goal of steeplechases similar to those at Alnwick, for upwards of a mile westward there was once a street called Michael's Grove, of which the site is now occupied by Ovington Square. This "Ovington" may be connoted not only with Offham Hill and Uffington of the White Horse, but also with Oving in Bucks, where is an earthwork also a spring known as "the Horse Spring," traditionally associated with Horsa.[440] Ovington Square at Kensington seems also to have been designated Brompton Grove, and as _Bronde_sbury, a few miles northward, was known alternatively as _Bromesbury_, and _Bromfield_, in Shropshire, as _Brunefield_, we may safely regard the _Brom_ which appears here, and in numerous Bromptons, Bromsgroves, Bromsberrows, Bromleas, also Brimham Rocks, as being the same word as _Bron_. The Latin name for broom--_planta genista_--apart from other evidence in my notebooks is an implication that the golden broom was deemed a symbol of Genista, the Good Genus or Janus: and as Janus of January, and _planta genista_, was the _first_, the word _prime_ may be connoted with _broom_. On 1st January, _i.e._, the first day of the first month, it was customary in England to make a globe of blackthorn, a plant which is the first to come into flower: we have already connoted the thorn or spica with the Prime Cause, and with the prime letter of the alphabet A, or Aleph, whence in all probability _bramble_ may be equated also with _broom_ and _prime_.
